1 Claim.

This invention relates to crow-bars and pinchbars, such as are commonlyused in construction, wrecking and repair work, and the main object orthe invention is to provide a tool of this kind that may be adapted foruse either as a conventional crow-bar having one end hooked and split atits extremity to form a nail puller, and the opposite end tapered oifangularly to form a prypoint or pinch-bar.

Another object of the invention is to provide a tool of the kindreferred to, made in two parts or sections hingedly connected end toend, one of the parts being hooked, tapered and split at its freeextremity to form a nail puller, and the other part being'an elongatedbar, tapered and sharpened at its free working end to serve as a pry-baror pinch-bar, and means for rigidly and releasably locking the two partstogether in longitudinal alignment and thus adapted to serve as aconventional crow-bar, or by releasing the lock and swinging the hookednail puller aside, to adapt the tool to receive hammer blows on the rearand blunted end of the pry-bar, for driving this bar to its work.

' With .the foregoing objects and advantages in view, together with suchother objects and advantages as may appear in the specification,attention is directed to the accompanying drawing wherein is embodiedcertain preferred forms of the invention, and wherein:

Figure 1 is a side elevation of the tool, the two sections thereof beingshown as supported in rigid longitudinal alignment by means of a collaror sleeve slidably positioned over the Joint of the two elements.

Figure 2 is a similar view, showing the hooked or curved nail pullersection swung aside and thus exposing the blunt end of the pry-bar tothe use of a hammer thereon for driving the working end of this bar toits work.

Figure 3 in a top side view of the tool as shown in Figure 1.

Figure 4 is an end view of the tool as shown in Figure 2, and lookingtowards the right end of that figure.

Figure 5 is a detail view in perspective on an enlarged scale of thelocking sleeve or collar.

The invention comprises two parts or sections, including an elongatedpry-bar 5, square in cross section as shown, having one end 6 turnedangularly aside and pointed or tapered as shown at l to form a pry orpinch-bar, while the opposite or rear end is formed blunt as shown at I,and is thus adapted to receive the blows of a hammer, for driving thetool to its work. The other part or section of the tool is in the formof a hooked or curved claw 9, having a squared and forked shank ill, theforks or prongs l l of which are formed and spaced to nicely setastraddle the squared end 8 of the bar 5, and to which it is hingedlyconnected by means of a heavy pin l2 passed through the extremities ofthe forks H and the rear end 8 of the said bar. The free extremity ofthe claw 9 is tapered, split axially and the split ends spread apart toform the nail pulling crotch l3.

A squared sleeve or collar I4 is provided and formed to nicely fit andslide upon the shank ll) of the hooked section 9 and over the inclosedrear end 8 of the bar 5, so as to rigidly lock this bar and hooktogether in longitudinal alignment for use as an ordinary crow-bar orpinch-bar. The said collar I4 is dimensioned so as to engage theelements with a suitable amount of friction,'s0 as to hold the collar inplace against accidental disengagement. If desired, and as shown inFigure 1, a conventional spring-set friction latch I5 may be seated inthe shank l0.

It is thought that from the foregoing description, the construction anduse of the tool will be fully understood. The tool with its partsrigidly aligned is adapted for use as an ordinary crowbar or pry-bar, oras a nail puller. With the nail pulling section released and movedaside, the remaining section may be used alone, and hammer blows uponthe blunted end thereof will serve to effectually drive the pointed endto the work.

While I have here shown and described certain embodiments of theinvention, and certain specific structural features thereof, thestructures and features shown may be varied as desired, within the scopeof the claim.

I claim:

In a tool of the kind described, an elongated pry-bar having one endpointed and the other end blunted to receive hammer blows, a hooked nailpulling claw having a forked shank set astraddle the blunted end of thepry-bar and pivotally pinned thereto, whereby the twoelements may belongitudinally aligned end to end. or the nail pulling claw may be swungaside, and a collar slidably mounted on the elements and adapted toslide over the Joint thereof. for holding the elements in longitudinalalignment.
